This was in a new save post update. I made the save the day before the pack's release. I'm not sure why the genetics are wonky when they age up. From what I've tested, it only happens with kids born to Grim.
Yes. Though what's interesting is that while the two boys have features from new Grim (one even getting his new nose), the girl looks like she got his old nose (which I don't know how since Grim is updated in this save and that is definitely not a nose I made, so not her mother's). I do love the look of the nose on her, but when I tried tweaking it for my bugged version, I couldn't fully replicate it.
